How much does an audit cost?

More than clients expect, often comparable to the development itself, and rising with complexity. That is the market rate for independent review of code holding value. Budget for it at the outset rather than treating it as an optional final step.

Can a contract be updated after launch?

Only if it was designed that way, using proxy patterns that separate logic from stored data. Upgradeability adds complexity and gives you a power some users will object to, so it is a decision to make deliberately at the start, not later on.

Which chain should we deploy to?

Depends on transaction costs, where your users already are, and what tooling you need. Ethereum carries the strongest network but the highest fees, while Base, Arbitrum, and Polygon cost far less. Most projects deploy to an EVM chain other than Ethereum.

Who is liable if something goes wrong?

That belongs in your contract with us and should be reviewed by your own counsel before either side signs. We reduce risk through testing and independent audit, but no development firm can absorb the value a deployed contract holds, and none will claim to.

Solidity
Development Services

Stateside Digitals provides Solidity development services, writing and testing smart contracts for Ethereum and other EVM chains, with the review and audit process that code holding real value genuinely requires.

Solidity is the language used to write smart contracts for Ethereum and the other chains running the same virtual machine. A smart contract is a program deployed onto a blockchain, where it executes exactly as written whenever somebody calls it, with no server of yours involved and nobody in a position to intervene once it has started running.

For a business, that carries an obvious appeal and a less obvious cost. Rules that execute automatically and cannot be quietly altered are genuinely valuable wherever trust between parties is the actual problem. The cost is that the same property applies to your mistakes, which is why this work is priced closer to safety-critical software than to a web build.

Runs Without A Server

The Chain Executes It

There is no infrastructure of yours to keep running, patch, or pay for once the contract is deployed and doing its job.

Rules Nobody Can Change

Including You

Participants can verify the terms will hold, which is the whole point, and the same guarantee applies to anything you got wrong.

Public And Verifiable

Anyone Can Audit The Code

Published source lets counterparties check what the contract does themselves rather than taking your description on trust.

Token Contracts

Standard-compliant tokens for payments, membership, or rewards, built on audited libraries rather than written from nothing.

Escrow And Settlement

Funds released automatically when agreed conditions are met, which removes the intermediary from transactions where both sides currently pay someone to hold the money.

On-Chain Records

Provenance, certification, and supply chain entries recorded where they can be checked independently and not quietly revised.

This is the difference that catches teams out. A defect in your application ships a fix on Tuesday afternoon. A defect in a deployed contract is permanent, publicly visible, and frequently exploitable for whatever value the contract is holding. There is no equivalent of quietly taking it offline for an hour while somebody works out what went wrong.

So the work is weighted differently from everything else we build. Far more of the budget goes into testing, review, and independent audit than into writing the contract itself, and the timeline reflects that rather than the number of lines involved. Where a contract will hold meaningful value, a third-party audit belongs in the plan from the start rather than after the code is finished.

We write Solidity against the OpenZeppelin libraries rather than reimplementing standards, building and testing in Foundry with fuzzing and static analysis through Slither. Contracts go to testnets before mainnet, with gas costs measured rather than estimated. We handle upgrade patterns, wallet integration through viem, and deployment across Ethereum, Base, Arbitrum, and Polygon.

Audited Before Deployment

Standard Libraries First

Testnet Before Mainnet

Upgrade Path Decided Early

Independent review happens while changes are still possible, because an audit commissioned after mainnet can only tell you what you already cannot fix.

Token and access control logic comes from OpenZeppelin, since code the whole industry has attacked for years is safer than anything written fresh for one project.

Contracts run under real conditions with real wallets and measured gas costs before anything touches a chain where the transactions are permanent.

Whether the contract can ever be changed is settled in the design, because retrofitting a proxy is not possible and the choice affects what users are being asked to trust.

Frequently not. If every party already trusts a central operator, a database does the same job for a fraction of the cost and can be corrected when wrong. Contracts earn their place where the absence of a trusted middle party is the problem being solved.
